: IMPROVEMENT IN SPINNING-RINGS.

Specification forming part of Letters Patent No. 116,160, dated May 23,1871.

' a full, clear, and exact description of the construction and operationof the same, reference being had to the annexed drawing making a part ofthis specification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawing is a representation of a horizontal section ofmy invention. Fig. 2 is arepresentation of a vertical section of thesame. Fig. 3 is an external view of the ring, showing it provided with aslot, 0. Fig. 2 is a central vertical section of the same. Figs. 5, 6,and 7 show my method of adjustment applied to a single-flanchspinning-ring. My invention relates to ring-spinning, and

. consists mainly in the novel construction of the ring and the rail, ashereinafter described, whereby the ring may be more easily held in placeand adjusted so as to be made concentrio with the spindle.

The letter A of the drawing designates the ring-rail, provided with theopenings B B for the spinning-rings D D, and the inner circular flanchesb b for the rings to rest upon. D represents my spinning-ring. It isprovided with a circular flanch, 6, both at the top and bottom, for thetraveler to run upon. therefore, reversible, and when one flanch is wornout the other may be used.

It is well known that in ring-spinning the great difficulty is to keepthe ring or the orbit of the traveler concentric with the spindle.Various means have been tried with more or less success. Myspinning-ring is flattened for a certain distance on each side thereof.

These flat spaces or planes are lettered c c on the drawing, and aresituated upon the exterior surface of the circular swell of thedouble-flanched ring between the flanches. These plane surfaces 0 c aredesigned to re- It is,

ceive the ends of the set=screws Z Z, which pass through the wall of theopening in the ring-rail, at its narrowest parts, or where thecircumference of the opening approaches nearest the edge of the rail.Thus it requires but little work to introduce the set-screws throughthering-rail. Sometimes, instead of flattening the. swell of thedouble-flanched ring, I form a groove, 0 therein, on each side of thering, in the middle of the swell, between theflanches.

My improved method of adjustment can be readily applied to the single-flanch rings in use by filing the necessary 'flat places on eachside of that portion which is seated in the rail, as {represented inFigs. 5, 6, and 7, in

which A- is the rail, D the ring, and c the flat places thereon; and butlittle expense is in volved in this alteration, as the set-screws areinserted in the ring-rail without much labor.

The advantages of economy andfacility of adjustment are attained bythese improvements, the adjusting arrangement being simple andinexpensive.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The ring-rail A, provided with a flange, b, in combination with thereversible doubleflanged ring having flattened surfaces cc or grooves c0 on the two opposite sides, and adjusted and held in position by buttwo sets'crews, as specified.

2. The ring D, having its neck provided with the flattened surfaces 0 con two opposite sides, so as to render it adjustable in the ring-rail Aby but two setscrews, Z Z, sub stantially as set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

WILLIAM T. CARROLL.
